Agnosticism is the belief in divinity without specification. Essentially that divinity exists but is unknowable. The ‘a’ also means without or against; Gnosticism being a religion principally dealing with the understanding of the nature of divinity.

Get out your dictionary, man. An agnostic is one who believes that it’s impossible to know if there IS a god or a future life, etc. Agnostics DO NOT believe that divinity exists (except for the delicius white fudge, which is hard to make).
